To r11/Z whom, Afit/,ty concern,.-

Be it known that l, Uniu's'rmn lCi'rLn, factory owner, a subject of the `KingI of AllfrteInberg, residing at 28/ litosen bergstrasse, in the city of Stuttgart, Kingdom of l/Vi'irtemberg, German Empire, have invented a certain new and useful Gras-lietort-Charging inlachine, of which the following-is a speci tieation.

This invention intended to provide means whereby the coal required for the manufacture of illuminating-gas fed to the red-hot retorts or furnaces in a layer of uniform height and uniform distribution throughout the entire length of the retort or the like for the purpose of distillation.

'lhe present invention provides means to secure a speedy and perilless feeding of the retorts and allows at the same time ot' the length of the same being considerably increased, so that it is about double the usual size, which is of extreme economical importance in the manufacture of illuminating-gas.

The apparatus is shown by way of example in Figure l in longitudinal section and in lTig. 2 in transverse section.

lt comprises chiefly any of the well-lmown centrifugal drums a, with wings /i rotating at the inside thereof, the helicoidal worm c as a feeding means, the storage-receptacle d, and a defleeting-plate e. All these parts combined are supported. by rollers in a suspension-frame ff, which is secured toa movable crane y, and

they may be vertically adjusted according` to the position ofthe retorts by means of a windlass )'1, with chain The apparatus is also provided with a device f, comprisingzit threaded piece operatively connected to the chain, and a wheel revolubly nlounted thereon` by means of which the apparatus may be raised or lowered to some extent independently of the windlass 71,. The dellecting-plate w is provided with a counter-lever connected to a toothed segment t, which engages with a worm. 'lhis defleeting-plate is positively connected to the lowering device and is operated simultaneously with the same, the loweringof the apparatus being eilieeted sinnlltaneously with and in a certain relation to the lowering ol the said plate.

'.lihe operation of the apparatus takes place in such a manner that the spiral worm e is re-N volved at the rame time as the blades l) of the centrifugal drum n.. llhe worm talles up the coal in uniform quantities and feeds it to the centrifugal drum, where it is thrown out of the delivery-optaring by the action of the rapid ly-rotating blades. ',llhe said deliver \1T-m)ening is so arranged as to be directed toward the retort or the furnace itis desired to charge with the coal, and it is so adl'iusted in a vertical direction as to .result in a maximum ol' throwing distance, by whiehineans theretorts are lilled at their extreme outer end. lly then gradually loweringl the apparatus simultallev ously with the lowering of the dellectingplate the throwingl distance is diminished, in proportion with the progress of feeding, and at the same time the momentum imparted to the coal bythe uniforudy-revolving blades reduced until the retort is filled throughout its entire length. l'rly increzrsing or reducing` the rate at which the apparatus is made to deu seend and the speed of lowering the deflecting-plate the ehargiiig of the apparatus may be adjusted so as to obtain any desired height of layer. llence the essential feature olv this invention resides in the tact that the centrili'ugal apparatus, which comprises, as usually, a centrifugal drum, a feeding-worm, astorame receptacle, and a deflecting-iilate, is provided with a lowering device which is operatively and positively connectrnl to the dellectingplate,` by which means any desired lengt-h of tl'irowingI distance with correspendingl speed ol' the throw is obtained while the speed of the throwing-blades remains unchanged, and thisl also results in the possibility of adjusting the height ol the layer, a result whichhas not been aceonipliahed before.

lfigure l shows the apparatus at the beginning of the charging operation, while the position shrnrn in dottei'l lines .indicates the position of the parts on the termination of the charging or rei-ation.

llligs. il and are representations of another torni of execution. ln this form olf4 construction the inclined lateral passages o o connect the centrifugal drum t with the storage-receptacle, which may be shut by a slide y). ln order to avoid the drawing in of cold air TOO While the Coal is thrust into the retort, which air would cause an injurious Cooling of the glowing' walls of the retort and which might give rise to explosions bv the mixing' with tine particles of coal, the exit-opening is provided with a protecting-plate n, which Covers the mouth of the retort at any level and which mayy be Withdrawn and may be again placed closely on the opening when the retort is being lled.

That I claim, and desire to secure by Letters Patent of the United States` isr l. In arnachine for tilling retorts, aeentrifugal drum, rotating blades mounted within the drum, afeed-oritice, a feed-worm in the feedorifiee, a storage-receptacle, a raising and lowering' device, and a delieeting-plate, substantially as shown and described,

2. In a m achine for lilling retorts, aeentrifugal drum, rotating blades mounted Within the drum, a feed-orifice, afeed-Worm in the feedorifoe, a storage-receptacle, a raising and lowering device, means for forming a tight lioint between the Walls of the exit and the retort'
